Because this project and the companion book are used in courses, at the
suggestion of several students I am no longer accepting contributions
of the existing styles written in different programming languages.
That is the first exercise that the students do. Having the solutions
easily available here will rob future students of the learning experience!

Please follow the conventions suggested by the existing code base,
specifically, if you are contributing a new style, make a new folder called
nn-funname and add an example program in that folder called
tf-nn.ext. (nn is the next avalaible number in the collection)
Additionally, add a README.md file that clearly describes the
contraints for writing programs in that style. I will only consider
new styles corresponding to constraints that are clearly different
from the ones that already exist in the collection. (different
programs written in existing styles are exercises for students, and
should not be here)

Contributions of new names and discussion should be done under Issues
or on the Wiki part of this repo.
